FRANK WARD MILLS, or LITTLE FALLS, NEW YORK.

THERMOSTATIC REGULATOR.

Specification of Letters Patent.

Patented Dec. 19, 1916.

Application filed January 8, 1916. Serial No. 71,068.

.To all whom it may concern Be it known that I, FRANK W. MILLS, a citizen of the United States, 7 residing at Little Falls, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Thermostatic Regulators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in thermostatic regulators for use in connection with heaters of various kinds and consists of a simple and eiiicient device of this nature having various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in-whichz Figure 1 is a top plan view showing the application of the invention to a heater. Fig. 2 is a side elevation, partly in vertical section. Fig. 3 is a sectional view taken on line 3-3 of Fig. 1, looking in the direction of the arrow.

Reference now being had to the details of the drawings by letter, A designates a heater and B a pipe passing through the same to be heated and through which water is adapted to run. Said pipe has a branching portion C, and D designates a tube having a closed end D and its other end open and circumferentially threaded and adapted to engage interior threads formed in the wall of an aperture I formed in the frame E, the latter having a reduced portion circumferentially threaded to receive the interior threads formed upon the pipe F. A carbon H is mounted within the tube D and one end bears against the end D and the other end, which is tapered as at H, bears against a metallic member O which is mounted in said aperture 1. The outer end of the member 0, which is tapering as at O, is adapted to bear against the short arm of the lever L, pivotally mounted upon the pin N carried by the frame. Bracket arms J rise from said frame and are spaced apart and carry a pivotal pin J upon which the rod R- is mounted, which has a weighted member R upon one arm thereof and its other end is pivoted to a link R shown in Fig. 2 of the drawings, which in turn is pivoted at R to the lever R which latter is pivotally mounted upon the pin R carried by the wall of the heater. A stem S of the damper S is pivotally connected to the long arm ofthe lever R and is adapted to regulate the opening S".

Two levers, designated respectively by letters T and X, are pivotally mounted upon a pin W, as shown in Fig. 3 of the drawings, and the lever X has a weighted end X and the other lever is pivotally mounted upon a pin T carried by the brackets T An adjusting screw T is mounted in a. threaded aperture in the long arm of the lever T and is adapted to bear against the frame and serves as a means for adjusting the same.

In operation, the damper S is normally open and, when heated liquid about the pipe D rises to a sufficient temperature, the pipe D will expand, allowing the weight upon the lever L to tilt the same and push the memher 0 against the end of the carbon H. The tilting of the lever L will allow the lever T to tilt upon its pivot T, causing the lever R to tilt and also the lever R through the medium of the link connection R therewith and which movement will throw the damper to a closed position. Vhen the temperature lowers, the tube D will contract and, as its inner end is in contact at all times with the inner closed end D of the tube D, said carbon H will be moved to the left with the tube D and the long arm of the lever L will be tilted up by reason of the member 0 pushing against its short end and which in turn will raise the lever T and cause a reverse movement to the levers R and R throwing the damper to an open position.

h at I claim to be new is l. The combination with a heater and a pipe communicating therewith and through which the heated liquid courses, a damper regulating the draft of the heater and a lever mechanism pivotally connected to said damper, a thermostatic tube, a carbon mounted in said tube, a member engageable with said carbon, a pivotally mounted lever having one arm engageable with said member, a pivotally mounted lever controlled by the movement of the first-named lever, a weighted lever pivotally mounted upon the secondnamed lever between its ends and controlled by the second-named lever and operatively connected with the damper mechanism, and means carried by the second-named lever and engageable with the first-named lever for adjustment of the first-named lever.

2. A thermostatic heat regulating apparatus comprising, in combination with a heater, a pipe communicating therewith and through which liquid courses, a frame, a tube having an opening therein fitted within said pipe and provided with a threaded end and extending within said pipe, a carbon Within the tube and bearing against the opposite ends thereof, its opposite end being tapered, a movable member within said opening and against which said tapering end bears, an angle lever pivoted to the frame, a bracket upon the latter, a lever fitted to said bracket a tilting lever mounted upon the frame and connected to the damper regulating levers and having a weight thereon and designed to be engaged by the clamping levers which are mounted upon said frame.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

FRANK WARD MILLS.
